Slack Feeling Lucky for Alfred
There is already an Alfred workflow for slack but it requires a custom Slack App. As far as I know, we can't install custom applications if we aren't the owner of the Slack group. I still wanted to be able to quickly open a conversation in Slack using Alfred. This solution might come out hacky but you can give it a try and maybe improve it.
Usage
Type slack <query>
and press return
to open Slack and open the conversation according to the query
